ProviderObject	Retrieves the underlying data provider object for the specified connection.
ServiceTypes	Retrieves a list of service types used to convert the unmanaged QueryService method call, in which a service GUID is specified, into a managed IServiceProvider.GetService method call, in which a managed type is specified. (Inherited from ServiceProvider)
Site	Retrieves or sets the site object instance. (Inherited from ServiceProviderWithSite)
State	Retrieves the state of the data connection.
